About this pattern

Explanation

にわたって is used to indicate that something extends across or throughout a range, space, or period. It emphasizes the entire span, not just a single point. It often appears with events, conditions, changes, or actions that affect or cover the whole range. In more formal or written language, にわたり is used as an alternative without て.
